At the end of charging the last light or the first light may remain lit but there is no charging going on as evidenced by monitoring the battery voltage with a digital voltmeter (voltage slowly goes down with time). I believe the chargers did work on the original K12S factory software load but not after the first upgrade so it may indeed be a software issue.
Very interesting. Mine "appears" to be working fine on my V 6.0 GT2.
It will be interesting see what comes of this. Please keep us posted.
